Application filed April 3, 1914, Serial No. 829,179. Renewed May 1, 1915; Serial No. 25,309.

To all whom it may cancem:

- Be it known that I, CHARLES HORN, a citizen of the United States, residing at Millbourne, in the County of Delaware and State of Pennsylvania, have invented a Combined Cable Clamp and Bushing, of which the following is a specification.

This invention is designed to provide improved means for securing electric cables to ontlet boxes, an object bein to obtain flexiblity that will permit satis actory clamping while providing a satisfactory bushing.

In the accompanying drawings, Figure 1 is a sectional elevation of my improved device 'combined with a box`and armored cable, taken on the line 1-1 of Fig. 2; Fig. 2

is a sectional view taken on the line 2-2 of ing between the rings, and

' therethrough.

.against the armor Fig. 1; Fig. 3 is a front elevation of an open box with the device therein; Fig. 4 is aperspective view of the detached device; and Fg; 5 is a perspective view of a modified form of the Construction.

The mechanism shown in Figs. 1 to 4 inlusive comprises a clamp and bushing havng the segmental bodies 1 provided with the mturne'd terminal rings 1 connected by the web 2, having the inturned flange 2 extendthe web sections 3, 3 and 3 separated by the slits 3, the web 2 havng a hearing 4: thereon. The device is engaged in the box 5 by a screw 6 which passes through the parts 3 and 4. Cables 7 provded with armor 7 are passed through apertures 5 in the bx With which the bores of the bodies-1 register, the ends of the armors '2' abutting against the rin gs 1 and the insulated covered conductors extending The cable being in place, the screw 6 s run in, drawing in the web secton 3 and pressing the extremities thereof a to clamp the cable securely. The box and cable are thus securely coupled together by a device that avoids injury to the covering on the conductors, and provides, the desired elasticity for clamping without sacrificing strength.

As illustrated in Fig.' 5; thecurved and hollow bodies 1 with the inturned terminal rings 1 are connectedby the web 2 with the inturned flange 2 extending between the rings, and the web sections 3' and 3 separated by the slot 3 the bottom rib 3 containing the notches 3 in its section comprised in the part 3 The slot 3 and the notches 3 permit the section 3 to be drawn' in readily and sectionsof the bodies at the ends thereof to be pressed in to secure more efl'ectual clamping.

Having described my invention, I claim:

1. In a device of the character described, a clamp and bushing comprising a pair of open bodies adapted for holding cables and webs connecting the terminals of said bodies, one of said webs being provided with a slot extending into said bodes.

2. In a device of the character described, a clamp and bushing comprising open segmental body portions provided with closed end rings and webs connectng said body portions, one of said webs containing a slot.

3. In a device of the character described,

a clamp and bushing comprising a pair of segmental bodies, webs connectng the extremities of said bodies, said bodes and one of said webs being provided with a slot, and means ccperating with said slot for facltating the flejxing of sections of said' bodies.

'In testimony whereofI have hereunto set my name this 26th day of March, 1914, in
